GitHub actions workflows require that the repository be named "openfast"

[rafmudaf]

Bug description In the GitHub Actions workflows, it is hardcoded that the path to the build directory is openfast/build. However, if the repo is named something else, the default paths will be different. In one case, this breaks the automated tests since libraries are loaded based on this assumed path.

Possibly replace all instances of openfast in a path with a GitHub Actions environment variable for the repo name

This is an extreme corner use case. We won't fix it.
